Donald Trump campaign manager Corey Lewandowski got physical with Breitbart reporter Michelle Fields last night when she tried to ask Trump a question at a press conference in Florida.

According to The Politico, which spoke to a witness on the scene, Fields was “clearly roughed up by the move,” which her boyfriend says on Twitter occurred “when she asked tough q.”

Fields was attempting to ask Trump a question as he exited the press conference. Secret Service was starting to clear a path, when Fields was forcibly grabbed on her arm by Lewandowski, moving her out of the way and nearly bringing her down to the ground, a source who witnessed the situation told POLITICO.

Breitbart, in a statement, confirmed most of the story.

“It’s obviously unacceptable that someone crossed a line and make physical contact with our reporter. What Michelle has told us directly is that someone “grabbed her arm” and while she did not see who it was, Ben Terris of the Washington Post told her that it was Corey Lewandowski. If that’s the case, Corey owes Michelle an immediate apology,” says the statement attributed to Breitbart News CEO and president Larry Solov.
